sert the alternative PAL and press down until it is fully seated. Make sure
that the alignment of the notch
at one end of the PAL is identical to the sur-
rounding chips. This will assure a proper pin-one match. Before restoring
power, change the jumper at W5 to the appropriate setting for the model you
desire. Table 3-3 shows the EPROM and jumper settings for each model.

Care must be taken when installing a CBI-I0I0 to avoid having the operating
system change the physical device names of the currently installed devices.
During auto configure, each device found is given a unique device name. The
device names are expressed as:
ddcu
where
dd = type of device (Le. MU,DU,PT,PU)
c = Controller designator (A,B,C ... )
u = Unit number
The device name is determined by the physical address of the controllers port
registers OP /SA). Since these addresses are fixed within the CBI-I0I0, there
are
no concerns with configuring the device type. Refer to Chapter 4, Table
4-1 for unit numbers.
The controller designator is derived by the operating system as it scans I/O
space. The first MSCP disk controller found is given the letter' A', the second
MSCP disk controller 'B' and so on. This will generate devices DUAx/PUAx,
DUBx/PUBx, incrementing the controller letter until all disk controllers are
found. The same is true for each
TMSCP tape controller, yielding devices
MUAx/PTAx, MUBx/PTBx and so on.
The scan will start
at node 0 and will work its way up to the last node ID
within the system. On native BI systems (Le. 8200/8250/8350), the node ID of
the BI is the system node ID. In these systems, the system ID's range from
o to 15.
